Profiles of racial discussions and associations with parent sociocultural factors and internalized racism in Asian American families.

While Asian American parents are key contributors in racially socializing their children, past research indicates that issues of race are not frequently discussed among Asian American families. Moreover, there is limited research on how Asian American parents' sociocultural factors predict the amount and ways they talk about race to their children. We conducted latent profile analyses among 150 Asian American parents' (Mage = 42.36, range = 26-65 years) racial discussions, and the profiles' association with parents' sociocultural factors (i.e., enculturation, acculturation, internalized racism, collectivism, and loss of face) were examined. Four distinct profiles were identified with distinct levels of awareness of discrimination, avoidance of outgroups, minimization of race, and promotion of equality messages. Findings underscore the importance of Asian American parents engaging in nuanced racial discussions with their children, highlighting the need for culturally responsive interventions, educational programs, and policy initiatives to support families in navigating complex racial landscapes and fostering positive youth outcomes.

Impact of lipopolysaccharide-induced acute lung injury in aged mice.

Study Aim: As the geriatric population rapidly expands, there has been a concurrent increase in elderly admissions to intensive care units (ICUs). Acute lung injury (ALI) is a prevalent reason for these admissions and carries poorer survival rates for the aged population compared to younger counterparts. The aging lung is subject to physiological, cellular, and immunological changes. However, our understanding of how aging impacts the clinical progression of ALI is limited. This study explored the effect of aging using a murine model of ALI. Methods: Female C57BL/6J mice, aged 7-8 wk (young) and 18 months (aged), were divided into four groups: young controls, aged controls, young with ALI (YL), and aged with ALI (AL). ALI was induced via intratracheal administration of lipopolysaccharide (LPS, 0.5 mg/kg). The animals were euthanized 72 h after LPS exposure. Results: The AL group exhibited a significantly increased wet/dry ratio compared to the other three groups, including the YL group. The bronchoalveolar lavage (BAL) fluid in the AL group had more cells overall, including more neutrophils, than the other groups. Inflammatory cytokines in BAL fluid showed similar trends. Histological analyses demonstrated more severe lung injury and fibrosis in the AL group than in the other groups. Increased transcription of senescence-associated secretory phenotype markers, including PAI-1 and MUC5B, was more prominent in the AL group than in the other groups. This trend was also observed in BAL samples from humans with pneumonia. Conclusions: Aging may amplify lung damage and inflammatory responses in ALI. This suggests that physicians should exercise increased caution in the clinical management of aged patients with ALI.

Associations among sleep-disordered breathing, sleep quality, and lung cancer in Korean patients.

PURPOSE: Intermittent hypoxia and sleep fragmentation, two main features of sleep-disordered breathing (SDB), have been shown to increase the aggressiveness of lung cancer, mainly in animal and in vitro studies. However, the association between SDB and lung cancer has not been well described in human studies. In this study, we investigated the associations among SDB, sleep quality, and lung cancer in Korean patients. METHODS: Patients with histologically diagnosed lung cancer performed a home sleep apnea test. Sleep questionnaires including the Epworth Sleepiness Scale (ESS), Insomnia Severity Index, and Pittsburgh Sleep Quality Index were also administered. Clinical information related to lung cancer was collected during the study. RESULTS: Sixty-nine patients were enrolled, 31 of whom were poor sleepers. The overall prevalence of SDB was 57% and that of moderate to severe SDB was 27%. Underlying chronic obstructive pulmonary disease (COPD) and smoking history were significantly more frequent in patients with moderate to severe SDB compared to patients without or with mild SDB. No significant differences were observed in the apnea-hypopnea index (AHI), oxygen desaturation index (ODI), or time with oxygen saturation < 90% (T90) according to cancer cell types, mutations, stages, and survival. However, small-cell lung cancer patients showed a trend toward higher AHI, ODI, and T90 values. CONCLUSION: The prevalence of SDB and proportion of poor sleepers were high in Korean patients with lung cancer. Paying more attention to sleep status may be helpful for patients with COPD, a smoking history, and small-cell lung cancer.

Cancer and COVID-19 Vaccines on Twitter:The Voice and Vaccine Attitude of Cancer Community.

We investigate social media discourses on the relationship between cancer and COVID-19 vaccines focusing on the key textual topics, themes reflecting the voice of cancer community, authors who contribute to the discourse, and valence toward vaccines. We analyzed 6,427 tweets about cancer and COVID-19 vaccines, posted from when vaccines were approved in the U.S. (December 2020) to the February 2022. We mixed quantitative text mining, manual coding and statistical analysis, and inductive qualitative thematic analysis. Nearly 16% of the tweets posted by a cancer community member mentioned about refusal or delay of their vaccination at the state/local level during the initial rollout despite the CDC's recommendation to prioritize adults with high-risk medical conditions. Most tweets posted by cancer patients (pro = 82.4% vs. anti = 5.1%) and caregivers (pro = 89.2% vs. anti = 4.2%) showed positive valence toward vaccines and advocated for vaccine uptake increase among cancer patients and the general population. Vaccine hesitancy, self-reported adverse events, and COVID-19 disruption of cancer treatment also appeared as key themes. The cancer community called for actions to improve vaccination procedures to become safe and accessible especially for elderly cancer patients, develop COVID-19 vaccines suitable for varying type, stage, and treatment of cancer, and advance cancer vaccines. Future research should continue surveilling conversations around continuous impacts of COVID-19 interference with the cancer control continuum, beyond vaccination, focusing on the voice and concern of cancer community.

Racial-ethnic socialization, racial discrimination, and internalization of the model minority myth in East Asian families.

Guided by the integrative model, this study investigated the moderating effect of East Asian American youth-reported (N = 143) racial-ethnic socialization (RES) in the relationship between the youth's experiences of discrimination and internalization of the model minority myth. The results suggest that there was a significant interaction between youth's racial discrimination and youth-reported awareness of discrimination on youth's internalization of the model minority myth (b = 3.52, p < .05). No significant interaction effect emerged between racial discrimination and maintenance of heritage culture on internalization of model minority myth. The findings offer several contributions to inform research, family, and communities in understanding the ways caregivers respond to youth's racialized settings, which also contribute to youth's positive outcomes.

Heated debates on regulations of heated tobacco products in South Korea: the news valence, source and framing of relative risk/benefit.

BACKGROUND: We analyse news representations of the regulation of heated tobacco products (HTPs) in South Korea, the country where HTP use is among the highest in the world despite conflicts between the government and the HTP manufacturers. METHODS: We analysed a total of 571 print and TV news covering HTP regulations, published between 2017 and 2018, the time period when HTPs were introduced to the country and various regulations of HTPs were proposed and implemented. We assessed the prevalence and associations among specific types of HTP regulations that were discussed, valence towards regulation, sources, framing of the relative health risks/benefits of HTPs compared with conventional cigarettes. RESULTS: Taxation (55.2%) and warning labels (25.7%) were two regulation topics covered the most. Almost equal proportions of pro-regulation (2.5%) and anti-regulation valence (2.2%) were found in taxation-related news, while pro-regulation valence appeared more frequently for other restrictions, including warning labels (pro=9.5% vs anti=1.4%), marketing restrictions (pro=6.9% vs anti=0%) and integration of HTPs into smoke-free policies for cigarettes (pro=8.7% vs anti=0%). The government (59%), followed by the tobacco industry (39.4%), was the source cited most often across news stories while the presence of tobacco control advocates was low (4.9%). As for framing, there was no significant difference in the prevalence of stories mentioning reduced harm (31.7%) and equal or more harm (33.6%) of HTPs compared with cigarettes. CONCLUSIONS: We provide implications for governments and tobacco control advocates on building consensus for applying cigarette equivalent taxes and pictorial warning labels to HTPs.

Metalloendopeptidase ADAM-like Decysin 1 (ADAMDEC1) in Colonic Subepithelial PDGFRα+ Cells Is a New Marker for Inflammatory Bowel Disease.

Metalloendopeptidase ADAM-Like Decysin 1 (ADAMDEC1) is an anti-inflammatory peptidase that is almost exclusively expressed in the gastrointestinal (GI) tract. We have recently found abundant and selective expression of Adamdec1 in colonic mucosal PDGFRα+ cells. However, the cellular origin for this gene expression is controversial as it is also known to be expressed in intestinal macrophages. We found that Adamdec1 mRNAs were selectively expressed in colonic mucosal subepithelial PDGFRα+ cells. ADAMDEC1 protein was mainly released from PDGFRα+ cells and accumulated in the mucosal layer lamina propria space near the epithelial basement membrane. PDGFRα+ cells significantly overexpressed Adamdec1 mRNAs and protein in DSS-induced colitis mice. Adamdec1 was predominantly expressed in CD45- PDGFRα+ cells in DSS-induced colitis mice, with only minimal expression in CD45+ CD64+ macrophages. Additionally, overexpression of both ADAMDEC1 mRNA and protein was consistently observed in PDGFRα+ cells, but not in CD64+ macrophages found in human colonic mucosal tissue affected by Crohn's disease. In summary, PDGFRα+ cells selectively express ADAMDEC1, which is localized to the colon mucosa layer. ADAMDEC1 expression significantly increases in DSS-induced colitis affected mice and Crohn's disease affected human tissue, suggesting that this gene can serve as a diagnostic and/or therapeutic target for intestinal inflammation and Crohn's disease.

Risk behaviors as correlates of victimization of U.S.-born and foreign-born Asian, Black, and Latinx adolescents in the United States.

The current study examines the association between risk behaviors and victimization and race-based victimization amongst U.S.-born and foreign-born Asian, Black, and Latinx adolescents. Data were derived from the U.S. subset of the 2009-2010 Health Behavior in School-aged Children study. Samples include 662 Asian, 2413 Black, and 3188 Latinx adolescents (M = 12.9, SD = 1.75, 48.6% female) in grades 5-10. Univariate analyses, t-test analyses, and multiple linear regression analyses were conducted. Aggressive behavior was associated with victimization for U.S.-born and foreign-born Asian, Black, and Latinx adolescents. Race-based aggressive behavior was correlated for U.S.-born and foreign-born Black and Latinx adolescents. Smoking was positively associated with victimization amongst foreign-born Asian adolescents. Alcohol use was correlated with victimization and race-based victimization amongst foreign-born Latinx adolescents. Marijuana use was related to victimization amongst U.S.-born Black adolescents. Physical fighting was shown to be positively correlated with race-based victimization for U.S.-born Latinx adolescents. Carrying a weapon was associated with victimization and race-based victimization for U.S.-born and foreign-born Latinx adolescents. It was also associated with victimization amongst U.S.-born Asian adolescents. Befriending deviant peers was negatively associated with U.S.-born and foreign-born Black adolescents and U.S.-born Latinx adolescents, but positively associated with U.S.-born Asian adolescents.

News Media Presentations of Heated Tobacco Products (HTPs): A Content Analysis of Newspaper and Television News Coverage in South Korea.

Our content analysis of newspaper and television news stories in South Korea examines the quantity and nature of news about novel heated tobacco products (HTPs), which heat instead of burn tobacco and that manufacturers claim are less harmful than cigarettes. The amount of news coverage peaked when the government introduced new regulations, suggesting that HTP news was driven largely by new policies. Indeed, HTPs were more likely to be presented as a policy rather than a health issue. When it comes to news sources, government agencies and HTP manufacturers were referenced most often in the news. As for benefits of HTPs, news stories focused on reduced harm, greater social acceptability, and convenience, while discussions of drawbacks included potentially being equally or more harmful than cigarettes, the possibility of extensive future regulations, and HTPs' unknown health effects. Findings suggested that certain journalistic practices, such as relying heavily on established routine sources, focusing on the stories that could attract large audiences, and representing the perspectives of the publishers and the primary audiences, might have affected the nature of HTP discourse.

Serial Screening for SARS-CoV-2 in Rectal Swabs of Symptomatic COVID-19 Patients.

We used serial rectal swabs to investigate the amount and duration of virus secretion through the gastrointestinal tract and assessed the association between fecal shedding and gastrointestinal symptoms and to clarify the clinical usefulness testing rectal swabs. We enrolled ten adult patients hospitalized with symptomatic coronavirus disease 2019 (COVID-19). Respiratory and stool specimens were collected by physicians. The presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was confirmed using real-time reverse-transcription polymerase chain reaction. All ten patients had respiratory symptoms, six had diarrhea, and seven were positive for SARS-CoV-2 on rectal swabs. The viral loads in the respiratory specimens was higher than those in the rectal specimens, and no rectal specimens were positive after the respiratory specimens became negative. There was no association between gastrointestinal symptoms, pneumonia, severity, and rectal viral load. Rectal swabs may play a role in detecting SARS-CoV-2 in individuals with suspected COVID-19, regardless of gastrointestinal symptoms.

Effects of chronic intermittent hypoxia caused by obstructive sleep apnea on lipopolysaccharide-induced acute lung injury.

AIM OF THE STUDY: Obstructive sleep apnea (OSA) is a common disease associated with significant morbidity and mortality. Sleep quality is an important issue; some patients with acute lung injury (ALI) have underlying OSA. However, the potential influences of OSA on ALI have not been reported until now. In this study, we evaluated the impact of preceding intermittent hypoxia (IH), a typical characteristic of OSA, on lipopolysaccharide (LPS)-induced ALI in a mouse model. METHODS: C57BL/6J mice were randomly divided into four groups: room air-control (RA-CTL), intermittent hypoxia-control (IH-CTL), room air-lipopolysaccharide (RA-LPS), and intermittent hypoxia-lipopolysaccharide (IH-LPS) groups. The mice were exposed to RA or IH (20 cycles/h, FiO2 nadir 7 ± 0.5%, 8 h/day) for 30 days. The LPS groups received intratracheal LPS on day 28. RESULTS: The IH-LPS group tended to exhibit more severe inflammation, fibrosis, and oxidative stress compared to the other groups, including the RA-LPS group. Total cell, neutrophil, and eosinophil counts in bronchoalveolar lavage fluid increased significantly in the IH-LPS group compared to the RA-LPS group. Compared to the RA-LPS group, the hydroxyproline level increased significantly in the IH-LPS group. In addition, the IH-LPS group exhibited significantly more terminal deoxynucleotidyl transferase dUTP nick end labeled-positive cells compared to the RA-LPS group. CONCLUSIONS: We found that prior IH may negatively impact LPS-induced ALI in a mouse model. This result suggests that ALI in patients with OSA may be more of a concern. Further research into the mechanisms underlying the effects of IH on ALI is needed.

Effects of long term normobaric hyperoxia exposure on lipopolysaccharide-induced lung injury.

Purpose/Aim of the study: Prolonged exposure to hyperoxia can cause injury to normal lung tissue. However, patients with acute hypoxic respiratory failure are frequently exposed to very high oxygen levels. This study investigated the effects of long term normobaric hyperoxia exposure in a mouse model of acute severe lung injury (SLI).Meterials and Methods: C57BL/6J mice were injected intratracheally with lipopolysaccharide (LPS, 4 mg/kg) to induce acute lung injury. After 2 h, mice were divided into two groups, and then exposed to room air or hyperoxic conditions for 48 h. Animals in the hyperoxia group were placed within their cages in a Plexiglass chamber with an atmosphere of 95% O2 maintained constant using an oxygen analyzer. After exposure to normoxia (N) or hyperoxia (H) for 48 h, the left lungs were collected for tissue paraffin block or oxidative stress assay. One lobe of the right lung was collected for lung/body weight ratio. The lung injury score and the mean linear intercept were evaluated in hematoxylin and eosin -stained lungs. The biochemical tests were performed by using ELISA assay.Results: Lung injury scoring, lung/body weight, and mean linear intercept were not significantly different between the N + LPS (NLPS) and H + LPS (HLPS) groups. Similar trends were observed in hydroxyproline and transforming growth factor-ß (TGF-ß) levels. Total cell and neutrophil counts in bronchoalveolar lavage fluid showed no significant differences between NLPS and HLPS groups. Histological analyses demonstrated more severe lung injury and fibrosis in the NLPS group than in the HLPS group. In addition, interleukin (IL)-1ß was significantly decreased in the HLPS group compared to the NLPS group. Other inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and IL-6, showed similar trends. The malondialdehyde (MDA) level was significantly lower in the HLPS group than in the NLPS group.Conclusions: Exposure to hyperoxia did not augment lung injury in the LPS-induced lung injury model, and some indicators even showed better outcomes. These results suggest that long-term high-oxygen therapy in patients with SLI has low risk of lung injury.

Association between triglyceride glucose index and obstructive sleep apnea risk in Korean adults: a cross-sectional cohort study.

BACKGROUND: Triglyceride glucose (TyG) index is a reliable marker of insulin resistance, which is linked to obstructive sleep apnea (OSA). However, the relationship between TyG index and OSA has not been adequately assessed. This study aimed to evaluate the association between TyG index and OSA. METHODS: TyG index was assessed in 180 (mean age: 48.6 ± 13.8 years; 73.9% male) consecutive Korean adults with suspected OSA admitted to the sleep clinic at St. Paul's Hospital between 2010 and 2012. The occurrence of more than 5 apnea-hypopnea index (AHI) events/h was used to define OSA. TyG index was calculated using the following equation: In [fasting triglycerides (mg/dL) × fasting glucose (mg/dL)/2]. All participants were grouped according to TyG index tertiles. Multivariate logistic regression analysis was used to determine factors associated with increased OSA risk. RESULTS: The overall prevalence of OSA in study participants was determined to be 83.9%. The prevalence of OSA increased (I [lowest]: 71.6%; II: 88.7%; III [highest]: 91.4%), and lowest peripheral oxygen saturation (SpO2) levels decreased (I: 83.3 ± 8.5%; II: 79.9 ± 8.7%; III: 79.0 ± 8.3%), as TyG index tertile increased (P < 0.05). TyG index was correlated with AHI (r = 0.179) and lowest SpO2 (r = - 0.188) (P < 0.05, respectively). Univariate linear regression analysis revealed an association between TyG and AHI (ß = 10.084; P = 0.016). Multivariate logistic regression analysis showed that TyG index (odds ratio [OR]: 3.348; 95% confidence interval [CI]: 1.081-10.372), age ≥ 55 years (OR: 5.426; 95% CI: 1.642-17.935), and obesity (OR: 3.801; 95% CI: 1.468-9.842) were associated with increased OSA risk (all P < 0.05). The optimal TyG index cut-off value for predicting OSA was 8.83 (sensitivity: 61.6%; specificity: 69.0%; area under the curve: 0.688; P = 0.001). The predictive value of the OSA cut-off value improved when age ≥ 55 years and obesity were considered. CONCLUSION: Increased TyG index was independently associated with increased OSA risk.

Perovskite Light-Emitting Diodes with Improved Outcoupling Using a High-Index Contrast Nanoarray.

Organic-inorganic hybrid perovskite light-emitting diodes (PeLEDs) are promising for next-generation optoelectronic devices due to their potential to achieve high color purity, efficiency, and brightness. Although the external quantum efficiency (EQE) of PeLEDs has recently surpassed 20%, various strategies are being pursued to increase EQE further and reduce the EQE gap compared to other LED technologies. A key point to further boost EQE of PeLEDs is linked to the high refractive index of the perovskite emissive layer, leading to optical losses of more than 70% of emitted photons. Here, it is demonstrated that a randomly distributed nanohole array with high-index contrast can effectively enhance outcoupling efficiency in PeLEDs. Based on a comprehensive optical analysis on the perovskite thin film and outcoupling structure, it is confirmed that the nanohole array effectively distributes light into the substrate for improved outcoupling, allowing for 1.64 times higher light extraction. As a result, highly efficient red/near-infrared PeLEDs with a peak EQE of 14.6% are demonstrated.

Tobacco Risk Information and Comparative Risk Assessment of E-Cigarettes Vs. Cigarettes: Application of the Reinforcing Spirals Model.

We examine how individuals seek information about e-cigarette risk and selectively expose themselves to media sources that may provide information consistent with their existing beliefs and behaviors related to e-cigarettes in application of the Reinforcing Spirals Model (Slater, 2007). Additionally, the associations among e-cigarette risk information-seeking, tobacco risk information exposure via media, and comparative risk assessment of e-cigarettes versus conventional cigarettes were identified. The results were compared among current users, former users, and those who had never used e-cigarettes ("never users"). A nationally representative data from the 2017 Health Information National Trends Surveys - FDA was employed. Our analyses suggest the presence of comparative risk perception among current users as assessing the health harm and addiction risk of e-cigarettes significantly lower than cigarettes. Current users did not avoid information about the health effects of e-cigarettes; they were more likely to look for such information than former and never users. Current users' e-cigarette risk information-seeking was negatively associated with the difference between perceived addiction risk of e-cigarettes and that of cigarettes. Current users' tobacco risk information exposure via social media was related with a lower level of the perceived risk of e-cigarettes, while such exposure via news media was related with a higher level of perceived risk of e-cigarettes. Our findings suggest the need for regulating and counteracting the prevalent e-cigarette information that discounts the relative risks of e-cigarettes as well as the potential of news media as influential sources helping current users scrutinize the risks.

The Influence of Parametric Uncertainty on Projections of Forest Land Use, Carbon, and Markets.

This paper uses Monte Carlo methods and regression analysis to assess the role of uncertainty in yield function and land supply elasticity parameters on land use, carbon, and market outcomes in a long-term dynamic model of the global forest sector. The results suggest that parametric uncertainty has little influence on projected future timber prices and global output, but it does have important implications for regional projections of outputs. A wide range of outcomes are possible for timber outputs, depending on growth and elasticity parameters. Timber output in the U.S., for instance, could change by -67 to +98 million m3 per year by 2060. Despite uncertainty in the parameters, our analysis suggests that the temperate zone may sequester +30 to +79 Pg C by 2060 and +58 to +114 Pg C by 2090 while the tropics are projected to store -35 to +70 Pg C and -33 to +73 Pg C for the same time periods, respectively. Attributional analysis shows that uncertainty in the parameters regulating forest growth has a more important impact on projections of future carbon storage than uncertainty in the land supply elasticity parameters. Moreover, the results suggest that understanding growth parameters in regions with large current carbon stocks is most important for making future projections of carbon storage.

Clinical subtypes and prognosis of pregnancy-associated breast cancer: results from the Korean Breast Cancer Society Registry database.

PURPOSE: We analyzed the clinicopathologic characteristics and prognosis of pregnancy-associated breast cancer (PABC) according to clinical subtypes to better understand the characteristics of PABC. METHODS: A total of 83,792 female patients between the ages of 20 and 49 were enrolled in the Korean Breast Cancer Society Registry database from January 1, 1996 to December 31, 2015. 'PABC' is defined as breast cancer diagnosed during pregnancy or within 1 year after delivery. Other patients were defined as 'non-PABC' patients. RESULTS: In non-PABC patients, luminal A subtype was the most common (50.2%). In PABC patients, TNBC was the most common (40.4%) subtype, while luminal A comprised 21.2% and HER2 subtype comprised 17.3%. There was a significant difference in overall survival (OS). In non-PABC patients, TNBC had the highest HR (HR 2.3, 95% CI 2.1-2.6). In PABC patients, the luminal B subtype (HR+ HER2-high Ki67) had the highest HR at 7.0 (95% CI 1.7-29.1). In multivariate analysis of OS by subtypes, PABC patients had significantly higher HR than non-PABC patients in the HER2 subtype (HR 2.0, 95% CI 1.1-3.7) and luminal B subtype (HR+ HER2-high Ki67) (HR 4.4, 95% CI 1.6-12.3). CONCLUSION: PABC showed different biologic features than non-PABC. PABC had a particularly poor prognosis in the luminal B (HR+ HER2-highKi67) and HER2 subtypes. To improve the prognosis of PABC, treatment should be considered according to subtype. Development of drugs that can be used during pregnancy is needed.

Identifying long-term survivors among metastatic breast cancer patients undergoing primary tumor surgery.

PURPOSE: The prognostic role of primary tumor surgery in women with metastatic breast cancer at diagnosis is contentious. A subset of patients who will benefit from aggressive local treatment is needed to be identified. Using a nationwide database, we developed and validated a predictive model to identify long-term survivors among patients who had undergone primary tumor surgery. METHODS: A total of 150,043 patients were enrolled in the Korean Breast Cancer Registry between January 1990 and December 2014. Of these, 2332 (1.6%) presented with distant metastasis at diagnosis. Using Cox proportional hazards regression, we developed and validated a model that predicts survival in patients who undergo primary tumor surgery, based on the clinicopathological features of the primary tumor. RESULTS: A total of 2232 metastatic breast cancer patients were reviewed. Of these, 1541 (69.0%) patients had undergone primary tumor surgery. The 3-year survival rate was 62.6% in this subgroup. Among these patients, advanced T-stage, high-grade tumor, lymphovascular invasion, negative estrogen receptor status, high Ki-67 expression, and abnormal CA 15-3 and alkaline phosphatase levels were associated with poor survival. A prediction model was developed based on these factors, which successfully identified patients with remarkable survival (score 0-3, 3-year survival rate 87.3%). The clinical significance of the model was also validated with an independent dataset. CONCLUSIONS: We have developed a predictive model to identify long-term survivors among women who undergo primary tumor surgery. This model will provide guidance to patients and physicians when considering surgery as a treatment modality for metastatic breast cancer.

"I Believe What I See": College Students' Use of Media, Issue Engagement, and Perceived Responsibility Regarding Campus Sexual Assault.

The topic of campus sexual assault has received much media attention recently, prompting scholars to examine media effects on students' attitudes and behaviors. A survey of 567 American college students examined how their media exposure is related to issue engagement, perceived responsibility, and acceptance of rape myths. Results indicated that reading newspaper stories about campus sexual assault might contribute to college students' victim blaming. Among other media channels examined, social media were found to be highly correlated with students' engagement with the issue. We also found that victim blaming and acceptance of rape myths could be reduced by raising students' perceived importance of the issue. Theoretical and practical implications are discussed in detail.

Local-Community Interests and South Carolinian Newspapers' Coverage of Smoke-Free Policies.

In this quantitative content analysis, we assess how smoke-free policies are presented in South Carolinian newspapers. In particular, this study examines the extent to which newspapers' coverage of smoke free-policies has represented the interests of their local communities. We compare newspapers in the communities whose economy relies heavily on the tourism and hospitality industry (The Post & Courier in Charleston and The Sun News in Myrtle Beach) and newspapers elsewhere (The State in Columbia and The Greenville News in Greenville), and see whether there are meaningful differences between the newspapers in the way they portray smoke-free policies, particularly in terms of their selective uses of news sources and key arguments. Our findings indicate that South Carolinian newspapers portrayed smoke-free policies largely as a political issue. Many political reasons to either support or oppose the policies were found in almost two out of three articles. We also found that The Post & Courier and The Sun News were more likely than The State and The Greenville News to make arguments against smoke-free policies, and this was particularly so when they were talking about economic impacts of the policies. Public health and media advocacy implications are discussed in detail.
